Kodi switched off after Argus TV Error prompt

Hi guys, first time using this so be patient!
I hv an ATV2 and Kodi won't wrk,as every time the screen comes up pops " Argus tv error connection lost" and switches the whole ATV off ;(
I still hv xmbc to tide me over but it's very temperamental!
But I hv to uninstall kodi to get xbmc to wrk!
Any help would be greatly appreciated thanks
